Conclusion

Achievement of research objectives are very important. In this study, the perception of risk factor was found as the main factor affecting slip-and-fall incidents. It was evident that friction was significantly affected by footwear material, type of floor, and the presence of contaminants on the floor. In addition, roughness also found consistent with the coefficient of friction (COF). According to human perception issue, the subjects could differentiate floor slipperiness under contaminated conditions but became unsure when in rating floor slipperiness for different types of floor
